Interface BooleanPredicate

  • All Superinterfaces:
    java.util.function.Predicate<java.lang.Boolean>
    Functional Interface:
    This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
    @FunctionalInterface
public interface BooleanPredicate
extends java.util.function.Predicate<java.lang.Boolean>
    A type-specific Predicate; provides methods to test a primitive type both as object and as primitive.

    Except for the boolean case, this interface extends both a parameterized Predicate and a type-specific JDK predicate (e.g., IntPredicate). For types missing a type-specific JDK predicate (e.g., short or float), we extend the predicate associated with the smallest primitive type that can represent the current type (e.g., int or double, respectively).

    Since:
    8.5.0

    • Method Detail

      • test

        boolean test​(boolean t)
        Evaluates this predicate on the given input.
        Parameters:
        t - the input.
        Returns:
        true if the input matches the predicate, otherwise false

      • identity

        static BooleanPredicate identity()
        Returns a BooleanPredicate that returns the boolean to be tested unmodified.

        UnaryOperator.identity()

      • negation

        static BooleanPredicate negation()
        Returns a BooleanPredicate that returns the negation of the boolean to be tested.

      • test

        @Deprecated
default boolean test​(java.lang.Boolean t)
        Deprecated.
        Please use the corresponding type-specific method instead.
        Specified by:
        test in interface java.util.function.Predicate<java.lang.Boolean>

      • and

        default BooleanPredicate and​(BooleanPredicate other)
        Returns a composed type-specific predicate that represents a short-circuiting logical AND of this type-specific predicate and another.
        Parameters:
        other - a predicate that will be logically-ANDed with this predicate.
        Returns:
        a composed predicate that represents the short-circuiting logical AND of this predicate and the other predicate.
        See Also:
        Predicate.and(java.util.function.Predicate<? super T>)
        API Notes:
        Implementing classes should generally override this method and keep the default implementation of the other overloads, which will delegate to this method (after proper conversions).

        Returns a composed type-specific predicate that represents a short-circuiting logical OR of this type-specific predicate and another.
        Parameters:
        other - a predicate that will be logically-ORed with this predicate.
        Returns:
        a composed predicate that represents the short-circuiting logical OR of this predicate and the other predicate.
